I've been looking into putting a coal stove in my basement. I have a small cape style house, about 1200 square feet. Lower level currently heated by an oil-hot air system, and upstairs by a few electric baseboards. I figure a decent stove in the basement should heat things nicely this winter. My question is this, the chimney for my oil burner does not appear to have a clean-out door. Is this necessary? If so, I'll look into a power vent, but i'd rather use the chimney if possible, as it's in the center of the basement and should make for better heat distribution.
